Awesome video. Got my profilometer in yesterday. I’ve been using Diamond and cbn hones for a few years now. They are a game changer for certain. I was very surprised by the amount of distortion registered around the top of the cylinder after the torque plate was removed on that block. With the head bolt threads being lower down in the cylinder I have seen some distortion around that region however I have not honed a Dart LS block only stock blocks and several LSX blocks. I’m curious as to how much distortion the lock wire is playing in that area. Nice video, nice work! Sure lends much confidence for me in my beginning processes of implementing a profilometer. Thank you for your time.
Yea its amazing how much distortion you can see in different blocks. I'm sure that fire ring makes a bigger difference than the traditional mls head gasket would. Glad it was helpful. Total Seal Pistons Rings is also a good source of information on cylinder surface finish.
Very interesting. Does dwelling cause a difference in the cross hatch angle at that location compared to the rest of cylinder? What machine adjustments are used to increase or decrease cross hatch? Thanks for the content.
Dwelling with a machine like this will cause a difference in cross hatch but we then stroke back over that area putting the cross hatch back. The newer machines and even cnc hones actually stroke a short distance when dwelling to keep the cross hatch angle the same. To change the cross hatch angle there are two drive belts on top of the hone that we can adjust in the different pulley grooves to change the speed of rotation and the speed of the stroke to get the desired cross hatch angle and well as for big changes in bore and stroke lengths on the blocks.
Just found your channel. Excellent video! You do a great job explaining the entire setup and honing process, as well as measuring the surface finish with the profilometer. I use a somewhat newer model CV-10 (white) which allows you to change the angle of the crosshatch pattern from the control panel. We use vitrified stones and a plateau brush for our honing process. I didn't realize that diamond stones were available that appear to fit the existing Sunnen stone holder. Most of the diamond stone set ups I've seen for the CV-10 involve a special honing head, usually having 4 or 6 diamond stones. $$$ Where do you purchase your diamond stones? What grit do you use on the vitrified stones for your final plateau hone? Kepp up the great work. Bill
Yea I ran across a few other people using these type of diamond stones and they are made and sold by Tennesse Abrassives and are designed to fit into the sunnen holder. They are a little on the pricey side compared to the vitrified stones but last a whole lot longer. The plateau stones are a sunnen 820 which is around 400 grit according to their catalog.
That is A way to hone cylinders not THE ONLY CORRECT WAY. If you want perfect, use induction heaters in all the bores first to heat things, remove the one your honing and see how much taper and out of round you get when things are at room temperature. (with torque plate in place) Your actually better to have top 1/4~1/3 at least 0.001" tight if you've never done 'correct' hot honing and are not set up for it. Current 'hot honing' is better but still not great in my opinion Looked about 73 /10,000" to me? Why don't you true the stones and how did they get so tapered in the first place? (blame the apprentice 😁) BTW, if you check the diagonals where studs are pulling there will be even more distortion than normal X-Y when you take torque plate off, even with a block as stout as that one. In the 80's, very few manufacturers gave surface roughness specifications plus vast majority of shops had never even heard of it

@@pageracingengines Thanks for the information.
@@uxbridgelibraryfriends8635 you're welcome
Awesome video
Do you hone Ford blocks?
Can you sneak up with this and perfect slight of of round by only removing material at the high
spots, aka minimum diameter.
*Out of round
What grit are you using to do the ruffing
According to the manufacturer it's around a 170 grit
@@pageracingengines ok
Nice video. What coolant are you using?
I don't have the exact number of the oil but I get it from Tennessee Abrasives, along with their diamond stones.
Probably high sulphur cutting oil?
Works much better than synthetic cutting/grinding oils in my experience.
How much would you charge to resleeve a lsa 6.2l

Вы забываете , что мотор у вас холодный и искажения не будут такими на горячем моторе
Then do this, um, then do that, um, then um measure um the um
Sorry , but the music is way too loud in your video!
Can't hear you talk over your music
